Hi,<BR> <BR>Our current system is running DRBD-8.0.6 on 2 boards, One of the baords is active and the other board is standby.<BR>DRBD is configured with meta-disk set as internal, port 7789, protocol C, size 9380. Excerpts attached at the end.<BR> <BR>To minimize outage by resetting both boards, we would like to upgrade and bring up standby board on DRBD-8.0.16 first. My attempts are not successful so far.<BR> <BR>Things modified to match DRBD-8.0.16:<BR>In drbd.conf file size is modified as "size 9380K"<BR>All other entries are kept same as in DRBD-8.0.6<BR> <BR>Issues:<BR>When drbd is started on standby drbdstatus shows <BR>0: cs:WFConnection st:Secondary/Unknown ds:UpToDate/DUnknown C r---<BR> <BR>And Primary does not detect DRBD on standby board.<BR>0: cs:WFConnection st:Primary/Unknown ds:UpToDate/DUnknown C r---<BR> <BR>Questions:<BR>1. Is DRBD-8.0.16 backward compatible with DRBD-8.0.6?<BR>2. Why there is no communication between DRBD-8.0.6 and DRBD-8.0.16?<BR>3. Can any one list all the changes one must do to upgrade DRBD version on a redundant setup (standby first and then active)?<BR> <BR>Excerpts from drbd.conf of DRBD8.0.6:<BR>disk {<BR> on-io-error detach;<BR> size 9380;<BR>}<BR> <BR> on Sc1 {<BR> device /dev/drbd0;<BR> disk /dev/tffsb4;<BR> address 10.19.17.1:7789;<BR> meta-disk internal;<BR> }<BR> on Sc2 {<BR> device /dev/drbd0;<BR> disk /dev/tffsb4;<BR> address 10.19.18.1:7789;<BR> meta-disk internal;<BR> }<BR><BR>Please do the needful,<BR><BR>Thanks and Regards,<BR>LAK <BR><BR><BR><BR><BR>
